You should see the wiring harness going up from the rear frame to up into rear wall. I tapped into two wires for the left side turn, running lights and brake. I couldn't locate the right signal light wire so I pulled back the side / rear skirting on right side rear and found the right side turn signal wire and tapped it and ran a single wire to the rear hitch along with the 2 wires from the left side (for a total of 3 wires) and the 4th wire (white) tied to chassis ground for the 4 wire plug on rear of hitch. It was a bit of a PITA. I've seem some owners tap into the lights at the pinbox connections and run a trailer 4 wire cable under the trailer (tie wrapped to bottom fabric) all the way back to the rear hitch. I don't recommend pulling anything heavier than 2500 lbs / 250 lbs tongue weight with that factory hitch.
If there is ever a next time, either get your car dealer to show you where the wiring harness is that the factory installed and tucked away, or if they didn't do that, buy a standard kit from either your dealer (expensive) or an auto parts store (cheaper) for you vehicle. They just plug into the existing wiring.
You are still not safe or legal to tow though.
